How to Choose the Right Charger for Your Laptop?

Some important factors are listed below which play a major role while purchasing a laptop charger.

1. Identify Your Charger’s part number

• Examining the label on your existing charger is one of the simplest ways to determine which charger is best for your laptop.
• On the label, the part number is typically written as “P/N”, “Spare”, or “FRU”.
• You can make sure that you buy the appropriate replacement charger for your laptop by determining the correct part number on the charger label. This can assist you in avoiding compatibility problems and guarantee that your device charges properly.

2. Identify Your Laptop’s serial/ model number

• Don’t worry if you can’t find or have lost your old charger, because there are still ways to get the appropriate replacement.
• One choice is to look for your laptop’s serial or model number, which is typically written on the back of the device.
• The serial or model number can also be located by using the command prompt. Simply type “cmd” into the Window’s search box, then “wmic bios get serial number” into the command prompt.
• By doing this, the model number will appear, which you can use to find the appropriate replacement charger.

3. Charger Connector Type and Watt

1. It is risky to find a replacement charger using only the model number. Because the same model occasionally has a variety of pin diameters or outputs.
2. If the pin type or size is incorrect, it won’t ever fit into the pin socket on your laptop to charge it.
3. A common way to identify the charger pin type is to physically check the pin type, measure the outer and inner diameters of your original pin and compare them to the diameters of the replacement laptop charger. And both of them have to match exactly, or it won’t fit at all.
4. Again, the incorrect output voltage also puts the components of your laptop at risk of being permanently harmed.
5. The charger’s wattage determines how quickly it can recharge the laptop battery. For instance, the output for the laptop charger mentioned above is 20V x 3A.

Wattage = Voltage x Ampere

It defines the laptop charger’s work at 20V voltage, 3A current, and 60W power.

6. You will need to ensure that the output specifications of your original and replacement laptop chargers are identical. To prevent the laptop charger from becoming damaged or overheating, it is essential to select the proper wattage.

4. How to choose the laptop charger’s replacement?

1. Getting the OEM or 3rd Party Laptop Charger

It might be difficult to find or even expensive to replace it from the original manufacturer (OEM). OEM laptop chargers come in two varieties.

1. Third-party AC adapters made specifically for the brand of laptop. The companies like Delta, ACBEL, and LiteON generally manufacture these types of products.
2. AC adapters produced by the laptop manufacturer itself. The companies like Samsung, Lenovo, and HP generally manufacture these types of products.

Always examine the branded logo on your original laptop charger while you are purchasing a new one.

2. Getting a universal Charger

A variety of devices including Bluetooth, smartphones, tablets, and laptops, can be charged using universal chargers.  The size of universal chargers is comparable to a phone charger.

1. Compatibility with Your Laptop: How to find the perfect charger match for your specific laptop model, whether it’s an HP laptop charger, Dell laptop charger, Lenovo laptop charger, or others.
2. OEM vs. Third-Party Chargers: Weighing the pros and cons, warranty considerations, and safety aspects of both options.

How to extend the life of your laptop charger?

10 simple maintenance techniques to ensure optimal charger performance and longevity.

1. Remove the charger’s plug when not in use.
2. Keep the charger away from extremely hot or cold environments.
3. Do not let the charger get too hot.
4. Avoid bending or twisting the charger cables.
5. Avoid using damaged chargers.
6. The charger connectors should not be forced.
7. Take care not to short-circuit the charger.
8. Never throw or drop the charger.
9. Avoid plugging and unplugging the charger.
10. Don’t use the wrong type of charger frequently.

Charging cycles of laptop chargers to improve longevity

The lifespan of your battery can be significantly shortened by repeatedly charging it at high voltages. According to [https://batteryuniversity.com/index.php/learn/article/how_to_prolong_lithium_based_batteries]

Charging a battery to just 85% to 90% of its capacity can increase its discharge cycle by 300 to as many as 1000 additional recharges.

Basically, you could extend the life of your battery by six to twelve months if you charged your laptop to 85% to 90% rather than 100%. Additionally, charging a battery to only 70% to 75% capacity can almost quadruple the number of discharge cycles.

1. After charging your laptop, try not to completely discharge it.
2. Keeping your battery level between 40% and 80% is the best thing you can do.
3. Make sure your laptop’s cooling fan is functioning properly and that it doesn’t become overheated.
4. The battery in your laptop can not “overcharge” and damage itself.

Conclusions:

Remember, your laptop charger is more than just a plug and cable; it’s the backbone of your laptop’s existence. Without it, your laptop would be nothing more than a sleek paperweight! So, give your charger the love and care it deserves by following some simple maintenance tips.

We’ve covered everything from the different types of chargers for popular laptop brands like HP, Dell, Lenovo, Asus, and Acer, to the wonders of universal chargers that fit almost any laptop out there.
